Abstract

FACCIONI, Samuel et al. Femoroacetabular Impingement - Factors Associated with the Presence of Deep Injuries of the Chondrolabral Junction. Rev. bras. ortop. [online]. 2019, vol.54, n.4, pp.434-439.  Epub Oct 07, 2019. ISSN 0102-3616.  http://dx.doi.org/10.1016/j.rbo.2018.04.003.

Objective

The purpose of the present study was to evaluate factors associated with the presence of deep chondral lesions (Konan/Haddad grades III and IV) in patients submitted to hip arthroscopy to treat femoroacetabular impingement (FAI).

Method

This was a prospective, cross-sectional study of a series of 125 consecutive hip arthroscopies performed between May 2016 and May 2017. After applying the exclusion criteria, 107 hips of 92 patients submitted to surgical treatment for mixed and CAM FAI were analyzed. For purposes of analysis, the present study considered groups with lesions considered mild and deep, which were associated with symptom score, lateral coverage angle, α angle, age, gender, and radiological classification of arthrosis. Results with a p-value < 0.05 were considered statistically significant.

Results

Patients whose hips had lesions considered deep had significantly higher nonarthritic hip scores (NAHSs) than those whose hips presented lesions considered mild or who did not present chondral lesions (67.9 ± 19.4 versus 57.0 ± 21.9, p= 0.027). The prevalence of deep lesions was higher in hipswith Tonnis 1 compared with hips with Tonnis 0: 15(55.6%) versus 10 (12.7%), respectively, p< 0.001.Men presented a higher prevalence of grades III and IV lesions than women, 23 (34.3%) versus 2 (5.0%), p= 0.001, and had significantly higher functional scores (65.6 ± 19.6 versus 49.3 ± 21.6, p< 0.001).

Conclusion

Men presented a higher prevalence of deep lesions. Hips classified as Tonnis 1 presented a 4.4-fold higher probability of presenting these lesions. Patients with deep chondrolabral lesions had a better preoperative functional score.
